The value of the surface area of a ractangular prism is equal to the value of the volume of the rectangular prism. Write and sol

Anuta_ua [19.1K]

The rectangular prism has measures 6 units by 6 units by x units,

Thus, the volume is 6*6*x = 36x (units cubed)

The surface area of the prism is

2(x*6+x*6+6*6)=2(6x+6x+36)=2(12x+36)=24x +72 (units squared.

36x=24x +72

36x-24x=72

12x=72

x=72/12=6

Answer: x=6

Step-by-step explanation:

Draw the triangle formed by the ray.

The hypotenuse of the triangle is:

c² = a² + b²

c² = (-5)² + (2√7)²

c² = 25 + 28

c = √53
